<h3 class="post-title">Groovy Goodness: Formatted Strings with sprintf</h3>

<div class="post">
<p>Groovy adds the <code>sprintf()</code> method to the <a href="http://groovy.codehaus.org/groovy-jdk/java/lang/Object.html"><code>Object</code></a> class. This means we can use the method in all of the classes, because it is defined at the top of the hierarchy. The <code>sprintf()</code> method uses the <a href="http://java.sun.com/j2se/1.5.0/docs/api/java/util/Formatter.html">Java Formatter</a> syntax to format values. We get a String as a result from the method.</p>
<pre class="brush:groovy">

assert 'Groovy is cool!' == sprintf( '%2$s %3$s %1$s', ['cool!', 'Groovy', 'is'])
assert '00042' == sprintf('%05d', 42)
